Background: Cancer patients are at a greater risk of malnutrition. Limited data exists on the development of malnutrition during chemo - radiotherapy, particularly in rural and remote areas of Australia. Additionally, there is no data on the nutritional status of cancer patients in the Northern Territory or areas with a high proportion of Indigenous Australians. While considering the aforementioned dearth of literature, we are conducting a study in Darwin, Northern Territory of Australia. This study aims to establish a baseline of the nutritional status of chemo - radiotherapy patients undergoing treatment at the Alan Walker Cancer Care Centre (Darwin), to identify contributing factors to nutritional deterioration, and to determine if there is a difference between Indigenous and non-Indigenous patients. This study will provide a prospective analysis of malnutrition and a clear insight of nutritional status of cancer patients. It presents the first of its kind to address the nutritional status of cancer patients in Indigenous Australians.
